摘　　要：图案代码显示是手工地毯编织的一个重要环节.传统的方法是将图案打印在普通纸上,由编织工人逐行阅读并进行编织.该方法不仅造成编织工人阅读困难,而且容易错码.为此,本文提出了使用大容量存储器和微处理器控制来实现图案代码显示的方法,并采用4 M 位的存储器和ATMEL的89C51 单片机实现了该显示器.设计中采用串口通讯和在线存储器编程方法实现代码写入,使用非易失性存储器存储操作状态以实现开机状态自动恢复.所设计的显示器不仅显示准确、阅读方便,而且具有很好的保密特性.Displaying rug pattern code is one of the most important parts of rug hand knitting.The traditional method is that the artists write the codes on the code book then the workers knit according to the codes.Because many symbols fill in a piece of paper,it is difficult to read for the workers.To solve the problem,a new method of using huge amount of memories and microcontroller to display codes is proposed in this paper.The designed display includes two main components of 4 Mbits flash memories and microcontroller ATMEL 89C51.To implement the function of code writing,the method that write codes by combining serial communication and on line code programming is used.To implement the function of auto restore,nonvolatile RAMs are used as the memories stored operation status.The code display designed is not only easy to read,but also have good security.
